git_ui: Only register conflict addon for full mode editors (#30049)
Noticed this whilst working on #26893
This PR prevents that single line and auto height editors have a
conflict addon attached (and are observed for any excerpt changes).
From how I understand it, it does not really make sense to register the
conflict addon for single line or auto height editors.
These editors will never show a conflict nor will they be used to
resolve one. Furthermore, neither of these ever have a project attached
upon creation:
https://github.com/zed-industries/zed/blob/00c5f57575b5de69a5007ba724b4a8fb10db91ac/crates/editor/src/editor.rs#L1385
https://github.com/zed-industries/zed/blob/00c5f57575b5de69a5007ba724b4a8fb10db91ac/crates/editor/src/editor.rs#L1403
https://github.com/zed-industries/zed/blob/00c5f57575b5de69a5007ba724b4a8fb10db91ac/crates/editor/src/editor.rs#L1415
so their buffers will never be added here:
https://github.com/zed-industries/zed/blob/00c5f57575b5de69a5007ba724b4a8fb10db91ac/crates/git_ui/src/conflict_view.rs#L116-L120
Thus, we could potentially even extend the check with an additional `||
editor.project.is_none()`. Yet, as I am not entirely sure how all of
this exactly works, I left this out for now, but I can definitely add
this if wanted.
